DOUBLE-LINE ROTARY PRESS.

Specification of Letters Patent.

Patented Oct. 25, 1910.

Application filed April 3, 1909. Serial No. 487,677.

Be it known that I, LYMAN citizen of the United States, residing at the city of Battle Creek, county of Calhoun, State of Michigan, have invented certain new .and useful Improvements in Double- Line Rotary Presses, of which the following is a specification.

This invention relates to improvements in double line rotary presses.

The objects of this invention are to provide a double line rotary press of large capacity in which the paging can bein multiples of two.

A further object is to provide an improved construction of integral or continuous electrotype or stereotype plate for rotary presses.

A further object relating to details is to provide a construction of press in which singleplate and double-plate stereotype cylindersmay be interchanged, wherebythe capacity of the press can run two, four, SIX, eight, ten, twelve, fourteen, sixteen, and

.multiples of two up to the capacity .of the press, which with plates two pages long, as illustrated, would be 32 pages.

A further object is to provide an improved means of supporting the, mandrels for such cylinders, making them accessible.

A still further object is to provide an, im-' proved construction of mandrel adapted for use in this relation. which is expansible whereby cylindrical plates may be adjusted and supported in any position thereon to sccure proper register, said tubularcylindrical plates beingadapted to ,be inserted .over the end of the mandrel and its adjustable shell.

Further obj eots, and objects relating to details ,of co11struc'tion,-will definitely appear from thefdetailed description to follow.

I accomplish the objects of my invention by thedevices and means described n the following specification.

- The invention is clearly defined point? ed out in the claims.

. A structure embodylng the features of invention is fully illustrated in the 'accompanying ,drawin-g, forming a part of this specification, in wh chz p v Figural 1s a. slde elevation View of a printing press embodying the features ofmy in.-

single intermediate use of with i'nterme iate gears G interposed betweenjthe upper perfecting mechanisms machine, the roll s'all being shown conventionally, the -details of the construction not being indicated. 'Fig. 3 is a plan view of the entire structure with the larger plate cylinders in place. Fig. 4 is a side elevation similar to that appearing in Fig. 1, in which the machine is adjusted for the full doubleplate or platesof even size throughout the -ent1re machine, like those appearing in Fig.

3." Fig. 5 is a sectional view, similar to the sectional view of Fig. 2, except that the rolls are all shown of the same size, either singleplate or double-plate. Fig. 6 is a similar sec tional view to Fig. 5 in which the machine is threaded up with a web for color work. Fig. 7 is a longitudinal sectional view taken on line 77 of Fig. 3. Fig. 8 is a transverse detail sectional view of the plate cylinder taken on line 88 of Fig. 7. Fig. 9 is a detail sectional'view on line 99 of Fig. 7 showing the detail of the'construction where by the end box is removable and the plate made accessible. Fig. 10 is a detail view of the gears which are in use when one of the perfectmg mechanisms is of the single page size. Fig. 11 isa detail sectional view, slmilar to that appearing in Fig. 2, showing a modified arrangement of the plate and 1mpression cylinders whereby different threading of the web is possible.

In the drawing, the sectional views are taken looking the direction of the little arrowsat the ends of the section lines, and

similar numerals of reference refer to simi- Considering the numbered parts of the drawing, the frame is made up of the sides 1-1 of the construction usual for double line presses. The particular press that I have illustrated here is made up of four erfecting mechanisms, two on the lower evel and two on the upper level, exactly superimposed, which perfecting mechanisms I will call A, B, C and D, respectively. These perfecting mechanisms are coupled together by suitable intermediate gears E and are driven from the gear F below. The ear E might be made mam shown this cutter 25 in conventional form, as appears in Fig. 2. The web 13 is brought up by suitable guides underneath this roll so that the page that is cut off travels upon it after it has been engaged by the feed rolls, and the whole is fed along together into the folder mechanism. I desire to comment in this behalf that, while the special. form of plate and means for supporting it is perfectly adapted to this form of press and is especially designed for it, yet the press itself will be very effective when arranged in this way, no matter how the plates may be supported on the cylinder, Whether they are the semi-circular plates or the full tubes, whether by some process the printing cylinders are made solid and are supported on suitable driven journals from the ends.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a double line rotary press, the combination of perfecting mechanisms arranged in tiers one above the other, each perfecting mechanism consisting of couples of printing and impression cylinders, the impression cylinders being arranged centrally and one above the other and the impression cylinders being geared to coact, the impression cylinders being provided with gears that mesh the one with the other, one set of such mechanism being provided with detachable boxes whereby the printing cylinders may be removed and those of a different size substituted, and suitable changeable intermediate gears by which the speed of such impression cylinders is made to correspond to their dimensi'ons; a folder; a cut-off feed mechanism for any web that is to move at a lower rate arranged in proximity to the folder whereby the severed sheet drops into the folder and is engaged by the more rapidly moving webs as they advance, all coacting substantially as described and for the purpose specified.

2. A ty 3e cylinder for rotary presses consisting o a tapered mandrel 18 suitably driven from a gear 23; an adjustable expansible shell 19; a nut 20 on a screw on the end of said mandrel for expanding the said shell 19 by pressing it onto the tapered mandrel 18; tubular plate cylinder 21 forming a closed tube or cylinder around the said expansible shell; and a removable support and box for the outer end of said mandrel to ermit the placing of said tubular plate cylinder on the said mandrel over the end thereof, all coacting substantially as de-' scribed and for the purpose specified.

3. A type cylinder for rotary presses consisting of an expansible shell; a tubular plate on the same, said shell being provided with supports and journal boxes, at each end, one of which supports and journal boxes is removable, whereby the tubular plate can be passed over the end of said cylinder and expansible shell, coacting for the purpose specified. I

4. In a double line rotary press, the combination of a series of perfecting mechanisms, each perfecting mechanism consisting of couples of plate and impression cylinders, the impression. cylinders being geared to coact with and being provided with gears that mesh the one with the other, one set of such perfecting mechanisms being provided with cylinders of half the diameter of the others, whereby multiples of the unit of the press may be effectively produced by combining the perfecting mechanisms having the smaller cylinders with the perfecting mechanism havin the larger cylinders; a folder and cut-o means for severing the web that moves at the lower rate from the smaller cylinder into sheets in proximity to the folder, so that they will be delivered with the more rapidly moving webs.

5. In a double line rotary press, the combination of a series of main perfecting mechanisms consisting of couples of plate and impression cylinders, of comparatively large size, capable of printing a plurality of pages on their circumference with gears for driving the same; a perfecting mechanism with plate cylinders of small size capable of printing one page on their circumference arranged to coact with any one or any combination ofthe remaining perfecting mechanisms of the series containing the cylinders of larger diameter; a gear connection for said smaller cylinder perfecting mechanism timed to rotate at the proper rate to deliver its single page, whereby multiples of the unit of the press may be effectively pro duced by combining the various perfecting mechanisms; a web guiding means for each perfecting mechanism; and a cutting mechanism for cutting the web of the small cylinder perfecting mechanism into-sheets, coacting as specified.

6. In a double line rotary press, the combination of a series of main perfecting mechanisms, consisting of couples of plate and impression cylinders, of comparatively large size, capable of printing a plurality of pages on their circumference with gears for driving the same; a perfecting mechanism with plate cylinders of small size capable of printing one page on their circumference arranged to deliver and coact with any one tively roduced by combining the various perfecting mechanism into sheets;' and a 10 perfecting mechanisms; a Web guiding means for each perfecting mechanism; a perfecting mechanism With full size printing cylinder With means of detachably securing the same in place whereby it can be substituted for said small plate cylinder perfecting mechanism and a cutting mechanism for cutting the Web of the small cylinder folding mechanism, coacting as specified.

In Witness whereof, I have hereunto set my hand and seal in the presence of two Witnesses.
